Title: Joint tube and manufacture thereof
Inventor: YOSHIDA TOSHIO
IPC: F16L47/00
Filed: 1990-07-17
Abstract: PURPOSE:To joint a tube positively and prevent the generation of flow stop in a liquid passage by forming a thick wall part on the tube end side of a tube made of fluorine group resin, and heat-welding the tube ends of the thick wall part to each other. CONSTITUTION:In a joint tube, the tube end side of the tube 1 made of fluorine group resin is formed into a thick wall part 2 by hot working so as to be thick on the outer side. The tube ends of the thick wall part 2 are then heated to be softened, and the tube ends softened by heating are press-fixed and heat- welded to each other so as to attain the expected jointing. As a result, smooth welding can be performed, and rigid and complete jointing can be achieved. In addition, the flow stop of liquid in a liquid passage is not generated.

Title: Floor heating appliance
Inventor: NOMURA MASAAKI
IPC: F24D7/00
Filed: 1981-11-27
Abstract: PURPOSE:To obtain a weight-saving, a uniformity of temperature distribution and an easy maintenance of the floor heating appliance of the type in which a heat accumulator and a heat exchanger are disposed under the floor by a  method wherein a heat pipe heat exchanger is arranged in the floor and an evaporation part is heated by hot water. CONSTITUTION:The heat exchanger 10 which is constituted by a closed vessel and a working liquid sealed in the vessel by an appropriate amount is disposed parallelly in and to the floor structure. In this construction, one end of the heat exchanger 10 is heated by circulating hot water to a heating means 20. Consequently, the working liquid within the heat exchanger 10 vaporizes and flows toward the other end of the heat exchanger 10, where it is condensed. In this while, the working liquid discharges heat through the wall of the heat exchanger 10 to heat the floor. The condensed liquid returns to the evaporation part 20 along the slope within the heat exchanger 10. According to this construction, the amount of hot water can be decreased, the heating temperature can be reduced and an even temperature distribution can be obtained. Further, the weight-saving of the heat exchanger can be realized.

Abstract: PURPOSE:To obtain a shutter which is easily reducible in size even if it is a setless type by extending a spring made of shape memory alloy between a shutter driving member and a release lever and heating this spring in response to a release signal. CONSTITUTION:Two sectors 2 which serve as diaphragm blades are energized by a closing spring 4 in closing directions and the shutter driving member 5 which drives the sectors 2 in opening directions is made by a return spring 6 to return naturally. The release lever 20 rotates around a spindle 20a to press the tip part of a release member 11 with the tip of one arm 20b and has a pin 20e on the other arm. Further, the spring 21 made of, for example, Ti-Ni shape memory alloy which is deformable at room temperatures and restores itself to its original shape at high temperatures is extended between the arm 5i of the member 5 and the pin 20e of the lever 20. Then, when the power source is turned on by releasing operation, the spring 21 is powered on and generates heat to shrink returning to its original shape. Its shrinkage in the former half swivels the lever 20 clockwise to push down the member 11 and the shrinkage in the latter half operates the member 5 to right against the spring 6.
